Does anyone use App::Prove::State, module which ships with the new Test::Harness? Outside of the Test::Harness distribution, the only code which I know of which uses it is a quick "which tests are slow?" hack I put together.
I ask this because I'm making some internal changes to this module. I am giving it a proper API to let people extend it in the future. I need to add new features for it, but said features can't live in the core (due to non-core dependencies) and as a result, I need to nail down the interface, but if anyone else is using it, I'd like to not cause them too much pain.
